Approach to Reporting

This Sustainable Development Report presents an overview of our Company, our approach to sustainable development, and the most material matters affecting Lonmin and its stakeholders.

The report is structured around chapters that present the context, significance, management approach and performance data for Lonmin’s five material focus areas. Additional information on certain topics is available in various supplementary reports and in our comprehensive GRI1 index.

The GRI (formerly the Global Reporting Initiative) is a global reporting guideline that provides a framework for sustainable development reporting (www.globalreporting.org). Lonmin’s GRI index is available online.

Scope and boundary

This report covers the financial year from 1 October 2016 to 30 September 2017. It discusses information relating to Lonmin’s subsidiaries: Western Platinum Limited (WPL), Eastern Platinum Limited (EPL), Messina Platinum Mines Limited (MPML), Akanani Mining (Proprietary) Limited (Akanani) and the Pandora joint venture. The report boundary includes the joint ventures and exploration activities over which the Company exercised management control during the financial year.

Significant changes to the Company

The closure of high-cost Generation 1 shafts continued as planned during 2017 in line with the re-organisation of the business announced in 2015. Newman shaft was closed during the second quarter of the financial year. The other Generation 1 shafts (Hossy, W1, E1, E2, E3 and Pandora) are managed as a coherent unit and some run by contractors, providing better flexibility to retain or stop them, depending on their profit contribution to the Company. E2 shaft was put on care and maintenance post year-end. Lonmin’s Chief Operating Officer (COO) resigned with effect from 5 April 2017. The Chief Executive Officer (CEO) took over the role in addition to his duties as CEO from that date.

Towards the end of 2017 and post year-end, Lonmin’s Operational Review focused on determining the best ways of preserving value for shareholders and safeguarding the long-term interests of employees and all key stakeholders. Post year-end, the potential transaction outcomes from the Operational Review have been superseded by the recommended offer from Sibanye-Stillwater to acquire Lonmin, which was announced on 14 December 2017. Further information on the offer from Sibanye-Stillwater and its impact on stakeholders will be contained in the scheme circular.
